Device FOR sT'oRiNo AND Aormnisremno sesiones.

SPECIFICATION forming pzut of Letters Patent No. 680,332, dated November 12, 1901. Application lc September 6, 1900. Serial No. 29.126. '.No model.)

To all whom. if muy concern:

13e it known that [,Uunnnnr F. Pansa m", a citizen of the United States, residing at. Detrait, in the county of Vt'ayne'and State of Michigan, have invented certain newand useful Innnm'emcnts in Devices for Storing and Administering Serums; and I do hereby declare the following to bea full, clear, and exact description of the invention, such as will enable others slailied in the art to which it appcrtains to make and use the same.

Myinveution relates to`improved means for storingand administering scrums; audits object, is to provide means.\\'hereby the serum will be retained out of contact with the air during all the time of storage, shipping, dispensing, and .-ulministering the same and to provide thc device by which this result is aecomplishcd with certain new and useful features hereinafter more fully described, and particularly.pointed outn the'elaims.

I have found that a. closure in the nature of a piston fitted loesclyenough to be moved in a cylinder and discharge its contents does not ctectually exclude the air. lxpelling the serum' by means of air is objectionable, as the air thus comes in Contact wit-li the sorum. I avoid these difficult-ics byproviding the piston with a stein .extending4 through a supplementary closure expressly adapted to exclude all air. I can thus fit. the piston loosely enough to operate t' reel y to 'discharge the .serum and at the saine time fnily exclude the air freni the scrum at all,timcs, as will more fully appear by reference tothe aecompanyiug drawings, in whiell-` Figure l is a side elevation of my improved storage, shippinggand dispensing vessel as it; appears when tllcd with serum; lflg. 2, a vcr tical scc-tien of the same as it appears when prepared ready for administeringr the serum, and Fig. f3 a detail of the hypodcrmic needle and coupling for attaching the same to the storage vessel.

Lilie letters refer to like parts in all ofthe figures.

A represents the 'vessel to contain the serum, which vessel consists of a cylindrical body, of glass orothersuitahle material, having,r at one end a reduced prolongation A A",

closed atthe end and having a transverse crease or groove l to facilitate breakage f the same at this place.

l) is a perforated closure, of eorl: or other suitable material, through the perforation in which passes the stem or handle l of the piserse the cylindrical body -t and expel the con` tents thereof, as hereinafter described.

F is a cap, of scalingavax, paraffin, or other suitable nmterial, surrnnmiing the stem E and efeetually sealing the passage in the closure I), through which tho stem passes.

G is a hypodcrmic needle, having attached a tubular rubber coupling Il, adapted to engage the extension A', as shown .in Fig. 2.

From the foregoingthc operationof mydevice will b c readily understood.

The cylinder A is made of suitable sizc to ing placed therein the piston C and supplelncutary closure D are t-heu inserted and the sealing-wax l` applied. The supplementary closure can thus be. made suxliceatiy tight and impervious to air to etcctually prevent any access of the same te thc scrum. In this condition 'the vessel containing the serum maybe stored, transported, or dispensed, and when vocefrsimiarises to administer the serum wax l" detached from the .stem lI by rotating ilu,- stcm or hy removing the wax. ingr the .stem E inward the piston C `will bo moved in thc body A and expel the contents thereof through the needle G.

After the contentsof the device have been used the device will .still he useful asa small syringe.

Having illus fully described my invention, what'. I claim, and desire to secure by Letters latent,'is-

reduced and closed extension adapted to be broken transversely, a piston in the cylinder,

iuder, and a supplementary closure, surrounding.; thcstcm, and impervious to air substantially as described.
